Tracking publisher email changes

2025-04-02

Chrome-Stats now detects and tracks changes to the publisher email address associated with Chrome extensions.

Why Does Publisher Email Matter?

The publisher email listed in the Chrome Web Store is a key piece of identity information for an extension's developer or owning entity. While changes can be perfectly legitimate – perhaps due to a company acquisition, rebranding, or a developer simply updating their contact information – they can also be a critical warning sign.

Unfortunately, we've observed scenarios where extensions, sometimes with large user bases, are sold or transferred. The new owner might then update the extension with malicious code, abusing the trust established by the original developer.

Tracking changes to the publisher email provides an early indicator of a potential ownership transfer that warrant closer scrutiny.

Introducing Publisher Email Change Detection on Chrome-Stats

Effective immediately, our systems are now monitoring for changes in the publisher email address listed on the Chrome Web Store. Here's how this translates into value for you:

  • New Risk Signal: A recent change in the publisher email is now incorporated as a signal in our risk likelihood assessment. While not definitive proof of malicious intent on its own, it adds a crucial data point, particularly when combined with other risk factors we track. You'll see this reflected in the data we provide for extensions exhibiting such changes.

  • Optional User Alerts: Knowledge is power. We understand that for specific extensions you monitor closely, knowing about an ownership or contact change is vital. You now have the option within your notification settings to receive alerts specifically when an extension you are tracking undergoes a publisher email change. This allows you to investigate promptly.

  • Proactive Warnings: Extension Guard will alert you if an extension you have installed has recently undergone a publisher email change. This brings critical information directly to your attention, allowing you to reassess the trustworthiness of an installed extension before a potentially harmful update is pushed.

Staying Ahead of Emerging Threats

Understanding the lifecycle and administrative changes of an extension adds another layer to a robust security posture. By tracking publisher email changes, we provide users and administrators with:

  • Early Warnings: Get notified of potential takeovers sooner.
  • Informed Decisions: Use this data point alongside others to decide whether to trust, monitor, or remove an extension.
  • Enhanced Visibility: Gain deeper insight into the administrative history of extensions.

We encourage you to explore the extension details pages on Chrome-Stats to see this new data point in action and to configure your alert preferences if desired.
